Use the account or previous-owner route first
If the device is linked to your Apple Account, recover access through Apple. If it belongs to a previous owner, ask that person to remove it from their account. They should never need to give you their password.
What proof of purchase is for
Apple’s support process may ask for documentation that establishes purchase and ownership. Use the official Activation Lock support request page for current requirements. A device identifier or third-party IMEI result is not the same thing as proof of purchase.
What happens next
Submit information through Apple’s official channel and wait for its review. We cannot access Apple’s internal systems, check a request, or predict its outcome. If you purchased the device from a reseller or marketplace, preserve your receipt and contact the seller as well.
Avoid sharing sensitive account details
Do not send your Apple Account password, device passcode, or verification codes to people claiming they can approve a request. Only submit requested documents through Apple’s official support process.
